A Note on Enneagram Books
Numerous books on the Enneagram are currently available, for example, see’s list of best-selling Enneagram books by other authors. Readers have become confused, however, by the inconsistencies and contradictions among them. We feel strongly that Enneagram books about relationships, business, spirituality-or about any other topic for that matter-will be of little use if they are based on distorted notions of the types or of the Enneagram as a whole.

For better or worse, there is no such thing as “the Enneagram”-only different interpretations of it by different authors. Those interested in this system are therefore urged to read all Enneagram books (including our own) critically, to think for themselves, and always to judge everything by their own experience. See the “Romancing the Enneagram” article and the FAQs page on this website for more information about recommended Enneagram books.
